Abstract: The present disclosure discloses a lighting lamp including a casing, a heat dissipating plate, heat dissipating fins, a light source plate, a power supply and a light transmitting member. The heat dissipating plate is spaced from the casing to form an annular passage. The heat dissipating fins are spaced along a circumference of a back side of the heat dissipating plate. A portion of each heat dissipating fin is located within the annular passage. The light source plate and the light transmitting member are located on a front side of the heat dissipating plate in sequence. The power supply is located above the back side of the heat dissipating plate. Heat generated by the light source plate and the power supply is conducted to the annular passage and is then carried away by air flow in the annular passage. The lighting lamp has high structural strength and high heat dissipation efficiency.
